All the equations can be graphed and solved by graphing. They can also be solved using various other methods
If the paintball is going 150m a second and the question asks, "starting from the distance of your friend what is the distance every TENTH of a second"
Ok so 150 meter a second so to get a tenth of a second you do 150/10 which is 15, if you start at 25 m away from you then only A and E could be correct, so now do 25+15 then that +15 and so on and you can see that letter choice E is correct
(x + 9)(x + 12) = 0
Expanding the brackets, we get:
Hello,
n=1,2,3,.... and not 0
Answer B a(n)=-2*n
Number eight is congruent
